Pick the format that matches your app or driver.

Useful for many app configs and environment variables.

mysql://root:[email protected]:3306/app_db?charset=utf8mb4

Common in Java and Spring-based applications.

jdbc:mysql://127.0.0.1:3306/app_db?user=root&password=secret&useSSL=false&characterEncoding=utf8mb4

Typical format for Python apps using SQLAlchemy and PyMySQL.

mysql+pymysql://root:[email protected]:3306/app_db?charset=utf8mb4

DSN format for PHP applications using PDO.

mysql:host=127.0.0.1;port=3306;dbname=app_db;charset=utf8mb4

Paste into Terminal for quick connection testing.

mysql -h 127.0.0.1 -P 3306 -u root -p app_db

After you generate the connection string, DartShell can help you keep SSH, file transfer, and database access in one Mac workspace.

Generate a MySQL URI when a framework asks for a single DATABASE_URL style string.

Use the JDBC format for Java projects, or copy the SQLAlchemy format for Python backends.

Use the mysql CLI output to test credentials and connectivity before wiring the database into your app.

mysql://app_user:[email protected]:3306/app_db?charset=utf8mb4

jdbc:mysql://db.example.com:3306/app_db?user=app_user&password=secret&useSSL=true&characterEncoding=utf8mb4

mysql -h db.example.com -P 3306 -u app_user -p app_db
